West didn't say he would. East's main contention was that she would have led a ♦ had she known it was a transfer.
Indeed, being told that there has been a misunderstanding has not negated the MI. East is also entitled to know that not only was 3D a transfer, but also that North bid 3NT over it without knowing it was a transfer (the failure to alert is AI for E-W only). There was presumably no systemic agreement for 3NT. I would lead a diamond against 3NT on this auction, but we should poll similar Easts and find out what they would do. I don't think West would double an alerted 3D - he would not want partner leading from Kx against a likely 4
♥.
And we also have the UI to consider, and presumably 3NT is undiscussed, so South will probably bid 4H as Cyberyeti states. North might interpret that as diamonds and hearts, and will probably pass, but we should poll Norths with the auction with 3D as natural - although very few would play that method. North has too much in the black suits to press on in my view.
I see it is Butler, and 3NT is always cold. So some percentage of 3NT = and some of it making overtricks. I have no idea what weighting, but it is not that critical.
I prefer to give the lawmakers credit for stating things for a reason - barmar
